I'm looking to source some high-quality storage and memory components. Specifically, I'm interested in M.2 SSDs and SATA drives. It would be great if you could provide me with a variety of options that you have in stock, including different capacities and performance levels. Additionally, details on pricing and availability would be appreciated. Furthermore, I need RAM modules as well, particularly PC4 RAM with 8GB and 16GB options. Please include any relevant specifications, such as latency and speed, along with your best pricing. I'm looking to make a bulk purchase, so I'd like to know about any discounts or special offers that might apply. Looking forward to your prompt response!
